use for tyre making platinum vulcanizing agent
Vulcanization (British: Vulcanisation) refers to a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice; however, it has also grown to include the hardening of other (synthetic) rubbers via various means.
Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins. Even with natural rubber, large amounts of sulfur as well as high temperatures and long heating periods are necessary, with the end products often being of an unsatisfactory quality.
The use of vulcanizing agent - rubber accelerator
The vulcanizing agent in conjunction with sulfur can prevent natural rubber reversion, improve its heat resistance, lower its heat resistance, make it aging resistance. The vulcanizing agent is used to load the tire shoulder rubber, rubber buffer layer, and solve the bias truck tire shoulder separation problem, and can also be used for large-sized thick products of natural rubber and a variety

Vulcanizing agents are substances that bring about the actual crosslinking process. Other properties, such as tensile strength, gas permeability, low temperature, flexibility and electrical resistance change with the degree of vulcanization. Each cross-linking releases a quantum of energy, making it an exothermal reaction.

Also, this rubber material is available in a range of hardness, which varies from soft to medium. Besides, the silicone rubber is first mixed with a curing agent or a vulcanizing agent to produce this material. As the catalyst, manufacturers commonly use either platinum or tin containing compounds such as dibutyltin dilaurate.
Applications. To produce the material, a use mixes silicone rubber with the curing agent or vulcanizing agent. Usually, the mixing ratio is a few percent. For RTV silicone to reproduce surface textures, the original must be clean.

During the build stage, the tire’s textile elements are placed in a specialty machine that ensures every part is in its appropriate place. The final step of the tire-making process is curing, which consists of vulcanizing the green tire with hot molds. Essentially, this step cures and compresses the tire to give it its end shape.
